Each of the wires l9 and, when they are shifted close to the panels I2 isformedwith a pair of parallel verlatter wires, spaces nearly as wide as the spaces 1 between said wires 19 are provided through which fowls may pass their heads to obtain feed from the trough. When, however, the wires 20 are shifted to points midway between the wires l9 the spaces between the latter wires are divided into two equal parts.

As a means for securing the carriage section in various adjusted positions upon the carrier section of the grating, clamping bolts 24 are provided, these being placed diagonally opposite to each other near corner portions of the trough, as shown. The lower ends of the bolts have heads 25 of a diameter slightly less than the width of the space between the rails of the track-like structures formed by the various paired rods which have been mentioned, said bolt heads each having a peripheral flange 26 of greater diameter than the width of said space. have each a Winged nut 21 screwing thereonto, the body portion of said nut having a diameter greater than the width of the space between the aforesaid tracl: railsi. By this track, clamping bolt andcarrier construction a means is provided for shiftably. supporting the grating wires 20 for 2d; adjustment longitudinally of the trough to the extent which has been indicated, and for releasably securing the two seetinns of the grating togetherlafter adjustment,

Owing to its hinged connection with the leaves 30:1 I! the entire grating structure may be swung to an openv position, as indicated by broken lines in Fig. 3, thus leaving the trough entirely unobstructed so that a new supply of feed may more readily be deposited therein. Each of the'panels %,;12 is shown having an inwardly directed top flange it, this portion of the right hand panel 52 (see 3 supporting the free edge portion of the grating struct "e when saidstructure is in its fully lowered position. v While 1' have shown and described a specific application of the invention I do notlimit myself thereto other than as set forth in the appended claims, and accordingly the invention embraces such changes and modifications as come within the meaning and scope of the claims.
